Change swift.proxy.server.Application.error_occurred()
to decode message as utf-8 in same way that the
exception_occurred() method was changed in [1].
This prevents a unicode error when logging error responses
in swift.proxy.controllers.base.Controller._make_request()
for paths that have non-ascii characters. Although the unicode
error is currently caught by a surrounding except clause, the
logging and error limiting treatment is different for ascii
vs non-ascii paths. This patch makes them consistent.
Fix the server type reported in _make_request() to be
the correct server type, not always 'Container Server'.
Fix path arg passed to _get_conn_response in
swift.proxy.controllers.obj.BaseObjectController to be req.path
rather than req.
Add unit tests for error_occurred() being called with non-ascii
paths and extend tests for exception_occurred() (see Related-Bug).
